Right now I use a gas grill, I want to buy a kettle grill for the summer, I know this sounds like a dumb question but you see the words "add more charcol", just how do you add additional charcol to the grill without taking everything off, etc?

Depends on what charcoal grill you buy. The Weber Kettle's grill has hinged areas on each side to allow you to put addtitional charcoal in as you are grilling. Works well. With some BBQ's you might have to jsut grab hold of the grill with the meat on it and set it aside while you add charcoal.

Remember, you should always use charcoal that has been started. Otherwise, you might get a bitter taste on your food. I like to use a chimney starter. They cost $10-$15. Worth the money.

As well the Patio Classic lineup of charcoal grills have a hinged grate to tend to coal during cooking without having to remove the whole grate. Smokers, both horizontal and vertical, have access doors for adding more fuel. If you equipment doesn't have an access door or a hinged grate then you must lift or remove your grate to add more charcoal.

Back to adding charcoal. As others have noted Weber uses a hinged grate. Other brands, such and Charbroil have a door on the grill body where you can add additional fuel. I believe a way to add charcoal is an absolute must on any serious grill.

If you use charcoal briquettes, they're fairly large and they don't break down and fall through the charcoal grate. When you use natural lump charwood - the chunks are smaller and they always fall through the charcoal grate. When you place two charcoal grates at the bottom of your weber, it prevents the charcoal from falling through.

I've also learned to add the crumpled newpaper to the chimney after I've dumped in the charcoal. Especially when getting towards the bottom of the bag. Seems the coal dust, if present in sufficient amounts, can choke out and snuff the starter.
